just a question on ih big truck engines, im having to sell my big kenworth dump truck so i can eat this winter, trucking around here isnt slow, its stopped, but im wanting to get a smaller say 6-8 yd dump so i can still work and pull my tractors around, ih is plenty good enough for me, in looking at the adds i see a variety of engines in the older ih trucks, [ i need cheap but runs] the dt 466 is a big truck engine isnt it? also in the same chassis class i see 7.3' ih, 5.9 cummins, and 8.3 also, so givin that total weight will be less than 30,000 which engine combination will be the best choise for power AND fuel economy also the most reliable, dont really need to stick with my kw's 4 mpg
